The study of water's occurrence, distribution, and movement on Earth, including its chemistry.

The study of the relationship between rocks and flowing groundwater.

Water that fills spaces in soil and rocks below the Earth's surface.

The continuous circulation of water on, above, and below the Earth.

Groundwater is a vital resource, supplying a significant portion of the world's fresh water for drinking, agriculture, and other human uses.

Surface water is found above ground in rivers, lakes, and oceans. Groundwater is stored underground in soil and rock formations.

A layer of rock or sediment that can store and transmit water. It's like a giant underground sponge.

A layer of rock or sediment that cannot transmit water. It acts as a barrier, preventing water flow.

A layer of rock or sediment that transmits very little water. It slows down water flow.

A layer of rock or sediment that cannot store or transmit water at all.

An aquifer that is sandwiched between two aquicludes. The water pressure is higher here.

An aquifer where the top is exposed to the atmosphere. The water table is the top of this aquifer.

An imaginary surface that represents the level to which water would rise in wells from a confined aquifer.

The area beneath the Earth's surface where all available spaces are filled with water. It includes aquifers and aquitards.

The area above the saturated zone where spaces in the soil and rock contain both air and water.

Groundwater movement is driven by differences in pressure and is influenced by the rock's permeability. In permeable materials, it can move quickly, while in less permeable materials, it can move very slowly.

The pressure exerted by water within a confined aquifer that causes water to rise above the aquifer's top level.

A confined aquifer where water pressure forces it to rise above the top of the aquifer, sometimes even to the surface.

Hydrogeology is crucial in understanding the movement and availability of groundwater, which aids in planning rescue operations like supplying water and managing potential flooding.

Construction activities can influence groundwater levels and quality. It can lead to pollution, changes in groundwater flow, and even land settlement.
